Which of the following substances or processes kills microorganisms on laboratory surfaces?
a. Antiseptics
b. Disinfectants
c. Degermers
d. Pasteurization

검증된 단계별 안내

Understand the definitions of each option: Antiseptics are chemicals used to reduce or inhibit microbial growth on living tissues, such as skin.

Disinfectants are chemical agents used to destroy or kill microorganisms on inanimate objects and surfaces, such as laboratory benches and equipment.

Degermers are substances or processes that remove microbes mechanically or chemically from living tissues, primarily to reduce microbial load but not necessarily kill all microorganisms.

Pasteurization is a heat treatment process used to reduce microbial load in liquids like milk, but it is not typically used for disinfecting surfaces.

Based on these definitions, identify which option specifically refers to killing microorganisms on laboratory surfaces, focusing on the role of disinfectants.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Disinfectants

Disinfectants are chemical agents used to destroy or inhibit the growth of microorganisms on inanimate surfaces, such as laboratory benches and equipment. They are stronger than antiseptics and are specifically designed for use on non-living objects to reduce microbial contamination.

Antiseptics

Antiseptics are substances applied to living tissues, like skin or mucous membranes, to reduce the number of microbes and prevent infection. Unlike disinfectants, they are safe for use on the body but are generally less potent against microorganisms on surfaces.

Pasteurization

Pasteurization is a heat treatment process used to kill pathogenic microorganisms in food and liquids, such as milk, without compromising quality. It is not used for disinfecting surfaces but rather for reducing microbial load in consumables.
